To all whom it may concern;

Be it known that I, MARY F. LooKn'rT, a citizen of the United States, residing in the city of Marion and State of Iowa, have invented new and useful Improvements in Spark and Soot Collectors, of which the following is a specification, reference being had to the accompanying drawings:

This invention pertains to spark and soot collectors forengines, and has for its object the reduction of. a device to collect the spar s and soot as same are blown frpm the smoke-stacks of locomotives or other engines, and to deflect same downward. into suitable receptacles, thereby preventing the fires which ordinarily result from such sparks being projected into combustible material.

Another object is to produce such a device in a simple, practical and efficient form, best adapted to carry out the purposes intended.

With these and other objects in view, attention is called to the accompanying drawings constituting a part of this application, wherein Figure 1 is a front elevation of one of my devices as attached to a locomotive engine;

Fig. 2, a vertical cross-sectional view;

Fig. 3, a detail showing the method of operating the rotary brush;

Fig. 4, a detail of the rotary brush;

Fig. 5, a detail of one ofthe spark boxes;

Fig. 6, a detail of the sparkreceiving cup.

Referring more particularly to the draw ings, my invention consists of a disk-like plate I mounted by means of a plurality of braces 2 over the top of the mp5. The cup 5 consists of a hollow annular ring 6 surrounding the smoke-stack 7, and fitting snugly against the smoke-stack. From the bottom of the cup 5 are downwardly extending flues 8, projecting into the spark receiving boxes 9. The apparatus is supported from the engine by means of suitable" braces as 10. Immediately over' the top of the smoke-stack and within the cage formed by the top plate 1 and the braces 2, is located a wire spark arresting cap or shell 11 made of suitable. wire screening or netting. Within this-foraminous spark arresting cap" into the spark boxes 9.

Specification of Letters 'Patent, Patented Feb. 10, 192(1 Application filed September 27, 1918. 7 Serial No. 255,911,

shaft 133s journaled at 14 and 15, projecting out to one side, and carries at the end. the small 'power wheel 16. 3 Downwa'rdly from this power wheel 16 extends a small belt 17 same running over and around the supplementary wheel 18. The periphery of the wheel 18 comes in contact with any suitable moving part of the engine, as for instance, the periphery of one of the front truck wheels as shown in drawings, whereby the brush is constantly rotated when the engine is in motion. a

In operation, it will be noted that when an engine isequi-pped with this device and under motion, the sparks emerging from the smoke-stack are projected against the top plate 1 and are deflected back into the cup.

5, whence they fall through the'fiues 8 down The wire cap 11 prevents the sparks and soot from being blown out sidewise into the open. The soot boxes 9 may be emptied as required.

While I have herein described a'certain specific manner and method of, constructing the elements of my invention, it is understood. that I may vary from the same .in-

minor details, not departing from the spirit of my invention, so as best to construct a practical device for the purpose intended, as defined in the appended claim.

What I claim to be new and patentable is z In a spark collector, the combination with a stack, .of an annular cup surrounding the stack at the upper end thereof and fitting the same, a foraminous shell mounted upon and forming a continuation of the walls of the cup," a deflecting plate extending across and forming an inperforate top wall for the shell, opposite braces connecting the said plate with the cup and holding the shell in place and provided with bearings, a h0ri-' zontal shaft extending across the shell and i i journaled in the said bearings and provided with arms and means for operating the shaft.
